A 20-year-old male patient presented to the dermatology outpatient department complaining of an abnormal, rough hair over his forearm of about 1-week duration. There was mild itching with no other significant symptoms. There was no history of any specific triggers, including insect bites. On clinical examination, the hair shaft appeared abnormal with surrounding hyperkeratotic appearance [Figure 1].

Dermoscopy (polarized light, ×10, Dermlite foto pro II) showed that the “abnormal” hair was actually a foreign body [Figure 2]. The foreign body was extracted with a fine needle which appeared to be an arthropod part [Figure 3]. Unfortunately, the given part was not sufficient to identify the specific arthropod.

Dermoscopy has been described as a useful auxiliary tool in the diagnosis of arthropod parts such as stingers.[1] We present this case to highlight the usefulness of dermoscopy in effectively diagnosing foreign bodies related to insect parts in the skin.
